IMPROVEMENT IN WATER-ELEVTORS.

TO ALL WHOMIfI MAY CONCERN: i

Be it known that I, .IoHN W. GRANNELL, of Yorkville, in the county of Kalamazoo, and State of Michigan.

haveinvented a new and useful Improvementon y Water-Elevators and I do hereby declare that theI follow' ing is a full, clear, and exact description of the construction and operation of the same, reference being had to thc annexed drawings, making a part of this specification, in which-w i Figure 1 is a perspective view.

Figure 2 is a plane view.

Similar letters of reference indicato corresponding parts in both figures. 4 My invention applies to that class of water-elevators invwhich a single water-bucket, A, is raised and lowered by'its attaching rope or chain 'B being wound or unwound on and from a drum-reel, D, the bucket being tilted and emptied into the discharging-spout s by any one' of two ear-catches, e, attached at opposite sides of the bucket, at a right angle to the points of suspension to the hail. E represents the well-curb, ot' ordinary rectangular construction, and F two standards, with bearings, in which the drum-rcel shaft S, provided with a crank, C, is hung. The drum-shaftcarries an overhanging ratchet-wheel, W, `with which aspring or jointed pawl, l?, engages, to sustain the loaded bucket in thc usual way, at any point in its ascent.

I usually construct the drum-reel D of cast metal, cored out in the centre, and into perforntions, all round the periphery ofthe shell, as clearly seen in lig. 1. At each end of the said perforated drum a recess or groove is formed by circular projecting flanges; that` at a1L being designed for winding around it a littleextra length of rope or chain, for facilitating the exact adjustment to the depth of the well. 'lhc other at a2, being intended for the reception of a combined brak.e-iron, J, and shifting-lever L, as will hereinaftcrbc morefully explained. The drum-reel is ltted to turn loosely on its shaft, with end play, and is only-dosigned to turn with it when moved by the shifting-lever, so that a clutch projection, o, on one end of the shaft, and a corresponding one, 0, on the head of the drum, are brought into working contact.

I curve the brake-iron .I so that it will embrace enough of thc periphery ofthe reel to croate the necessary l friction, and pivot it to the end of the lever, which Ijoint to a stud, G, provided with a pin, to be inserted ina Vsocket in the well-curb, so that the stud will turn a little in its seat. A hooked rod, keeps the drum coupled with its shaft.

For reasons to be explainedin describing the mode of operation, I do not in myarrangcment suspend the water-bucket by an ordinary bail, 'but instead thereof connect two long branch ropes or chains to the main. one,

as at b b, and attach in any convenient way their ends to the side of the bucket, at such pointslas will allow it to till and fill readily in the well. T represents an ordinary cranked tilting-rod, which is hung to the sides of the curb, and te the usual trough and spout for discharging the water.

The operation is as follows: As the operator turns the crank in the direction of the arrow, the clutched i drum will turn, when the full water-bucket will ascend,'as in any winch, by the rope or 4chain being wound around the drum. When the forked or branch portions oi' the rope reach the drum, they will spread over it and cause one or the other'side of the bucket to be p roperly presented, so that one `of the oar-catches c will hook on the tilting-rod T, which will turn, and the bucket be drawn forward,- tiltcd, audits contents discharged,

substantially in the ordinary way, The operator then unhooks the shifting-lever, and presses it sidcwise, so as to unclutch the loose drum from its shaft, when the empty bucket will descend into the wclltoV bereiillcd, `by reason of its weight causing the loose drum to turn on its then stationary shaft in a contrary direction from before, thereby unwinding the rope or chain. My object in connect-ing the bucket to the hoistng-ropo bythe longrope or chain-bail, is for the purpose of having a double bearing aroundxthc drum, as may be clcarlyseen iultig. 2, to insure thc proper presentation of one er the other ofY the ear-catches to the tilting-rod, as aforesaid, and to prevent'the oscillation of the bucket when the drum is unelutched by a. sudden end motion.` I make the drum hollow, and cnstlit with perforations to .allow the air to circulate through it, and aid in drying and `preA serving the rope. 'As soon as the bucket begins to descend the operator 'presses downwards `to apply the brake J', and regulate the motion of the empty bucket.' As soon as the bucket is illed the lever is hooked fast, and

'the drum clutched for lifting the filled bucket as before.

I do not claim broadly lowering the single bucket without revolving the crank-shaft, for that is-not new:

but I aim not aware that any such mode as .mine of conneqtng the hostngrope o1* chain with the bucket' has even before been used with loose perfoljated drum, operaitell Aas herein described; therefore, whatl claim :is

my invention, and desixeto secure ly Let-ters Patent, is

I claim the ombinmton 'of the loose flanged drum D and attaohed rope and bucket, with the cragnk-slmf't SQ -clutches o o, shifting brake-lever L, pivot stud G, and hoek II, arranged, connected, and'opex'atcvd substantially as and fol the purpose herein specified.
